Curtate cycloid program needs update

[violins88]

I have a cycloid program varch.zip on my website https://jpschmidtviolins.com/Varch12v2.zip

apparently Windows stopped supporting zip files. A violin maker In France wants to use it. Can one our Maestronet geniuses tell me how to change a zip file to a useable format?

 

I know you are out the. Need your help.

I'm pretty sure windows (even the problematic 11) has built in support for .zip archives.

What is the problem you are encountering?

[violins88]

The user said she could not get it to work, as in run. I just tested it with windows 11. It would not open.

I could put you in touch with her.

thanks

W11  or W10 or any. Find where you downloaded the zip file to and right click on it. Choose 'Extract all" from the list of options. accept the default location but make not of it. That's where the unzipped program files will be.

Next step --- open the unzipped folder and find the setup.exe file. Double click on that and run it. Windows asks if you want it to make changes, say yes. Record the directory it says it will install to  or change it to a more friendly directory. Find the arching program in that directory and run it. It is called 'violinarch.exe". Make a shortcut to it on your taskbar start menu or desktop.

 

I did all this just now in W11 as I was typing. McAfee antivirus did not object to anything.

Zip worked here also, running windows 11, and application installed

LCF just beat me. When you asked I downloaded the file and unzipped it here with no problems.

W11 can deny running many older programs or drivers. Certainly as LCF pointed you need to extract files first and only then run the installation file otherwise (if you just open the archive and run the file directly from inside) it will fail to find it's resources needed to install.

Carl1961 (so young!) this is off this topic but I have been wondering what software you used to dissect and edit the original Betts Strad 3 D scan file? I found it had lots of difficult artefacts and it was a bit if a b#$+@%d of a file to work with. I managed to resin print a scaled down version of the back plus some ribs using Lychee slicer but I'd like to try running it into gcode.

I used https://download.slicer.org/ to load the Dcon files,  but as for the stl file I got it way back here on a betts post that a guy uploaded. I use fusion 360 to edit and mess with the stl file.  it is so high resolution fusion 360 take a while to render. but without the high resolution, parts do not look right. for 3d printer slicer I use Simplify 3d and Cura , latest cura is even better than simplify3d now. https://ultimaker.com/software/ultimaker-cura/

I followed the instructions by LCF with success. Thanks to LCF  and to everyone. John

This program looks incredibly well designed.

For me and my PC running windows 10 it still doesn't work... 

I'm not giving up hope of finding a geek in my circle who can solve the problem.

download 7zip and use it to unzip.          https://7-zip.org/

Thanks for reminding me why learning to use Matlab (R) was time well-spent.

How do you handle the infill in a Matlab(R)  version of slicing?

[Dr. Mark]

So I guess I'm a little unclear - do you mean using interp(), or setting the interval delta-phi between successive datapoints using something like phi = 0:(desired delta-phi): pi; (say)..... when calculating the cycloid x and y vectors x(phi:a,b) and y(phi:a,b), or...?  Here a and b are radii of the outer and inner circle of a curtate cycloid respectively.

I guess if we're in the third dimension (say z), i.e. moving up or down the plate and talking about the density of cycloids, I suppose we'd have to decide how we'd want each successive cycloid scaled as a function of z, then what density of cycloids we want to calculate.  We may or may not benefit from a relatively sparse number of cycloids and interpolate between pairs of points of adjacent pairs of cycloids.  Linear might look faceted, but we could probably do pretty well with a polynomial curve interpolation, which would be continuous.  If we can't get the whole plate with accuracy we could do, say three or four at a time.  I don't see any reason not to collect cycloids though - it's not like the program has to run in 20 msec or fail.

We may also want to vary the position of the inflection point, and we'd have a lot of leeway if we used non-linear scaling although that may be overkill.  The inflection points are the local extrema of the slope on a given cycle, so we could let matlab run through and compare (yj - yj-2)/(xj - xj-2) to obtain a numeric estimate at (xj-1,yj-1), or calculate the parametric extrema before hand i.e. (dphi/dx)(dy/dphi) and let ML do the calculation.  But I'm babbling now....we may be able to use an intrinsic function like surface() or contour(), at least for display.  (R) by the way was my attempt to indicate a registered trademark.

Young Carl was discussing the complexities of working with various types of 3D cad files and 'slicing' them for 3 D printing. Infill is one of the considerations in 3D filament printing.

 

Resume.

Here's a few ideas about not being able to extract from zips with Windows.
